Each time Thomas performed sex acts, she would have her son wait in the bathtub until she and her client were finished, according to officials.

Police got a tip from Thomas’ sister that led them to Mall Motel in Trevose, Pa. near the Neshaminy Mall. Police observed the operation, then were able to stop a "John" who was leaving her room. Officials then had him call Thomas to say he was sending over a friend. The "friend" was really an undercover cop.

The condition of the room and bathroom was filthy with trash and garbage everywhere and a strong odor of urine, according to police.

Thomas is locked up on $20,000 bail, charged with prostitution, possession of drugs and paraphernalia and endangering a child.

Her son is with Bucks County Family Services. The three dogs were taken to the Women's Humane Services.
